2020, Electric Power Systems Research Citation Excerpt : Despite the improved quality of the measurement devices, it is important to have a State Estimator (SE) that delivers information about the dynamic variables (e.g. rotor angles and mechanical velocities) and algebraic states (bus voltage phas...
The state estimator (SE) is the tool currently used in power systems for real-time monitoring. Because current SE techniques become operationally expensive on such large systems, it is beneficial to consider alternate methods for wide-area state estimation (WASE). In particular, hierarchal methods ...

The accuracy of the adaptive, data-driven LPA-RICI based state estimator was tested on the IEEE test systems with 14 and 30 buses, as well as on a model of the real-life Croatian transmission power system. Due to its adaptivity to high transitions in measurement series achieved by varying ...
This paper describes a simple, reliable and very fast estimation algorithm for on-line analysis of ill-conditioned power systems. The estimator proposed is decoupled in nature and is suitable for on-line sequential processing of measurements telemetered, either one at a time or in batches. The ...

An accurate and dynamically robust state estimator is indispensable for the efficient and reliable operation of a power system. In this paper, a state estimation method based on Phasor Measurement Units (PMUs) is proposed for the real-time monitoring of power systems under various operating condition...
